OBJECTIVE: To investigate the effect of acupuncture therapy on fracture healing in rats with femur ***: A total of 10 groups were formed;control group, groups sacrificed on 7 th, 14 th, and 21 st days of fracture formation, groups to which acupuncture was applied for 7, 14, and 21 d, groups to which fracture and acupuncture were applied for 7,14, and 21 d. A transverse fracture line was formed in femurs of rats by using a Gigli saw. The Kirschner wire was driven retrograde down from the fracture line to proximal part of the bone and then, the fracture was fixed towards distal part. Acupuncture was applied to the rats for 7, 14, and 21 d as 4 sessions per week after formation of the ***: Malondialdehyde(MDA), reduced glutathione(GSH) levels, catalase(CAT), glutathione-Stransferase(GST), superoxide dismutase(SOD), and glucose-6-phosphate dehydrogenase(G6 PD) activities were measured. Despite the increased MDA levels, G6 PD and SOD activities reduced during the fracture healing. There was a statistically significant increase in MDA, GSH levels, and G6 PD activity in fracture groups compared to control group, but CAT, GST, and SOD activities decreased. The use of acupuncture enhanced callus development and bone mineralization during bone ***: The acupuncture therapy can affect suppression of the effects of free oxygen radicals and regulation of the antioxidant enzyme activity in fracture healing. Thus, it is suggested that acupuncture treatment would be beneficial for fracture healing in order to eliminate the negative effects induced by oxygen free radicals.

Left Atrial Mechanical Function and Aortic Stiffness in Middle-aged Patients with the First Episode of Atrial Fibrillation

Chinese Medical Journal 2017年第2期130卷 143-148页

Background： In the early stages of atrial remodeling, aortic stiffness might be an indication of an atrial myopathy, in particular, atrial fibrosis. This study aimed to investigate the association between left atrial （LA） mechanical function, assessed by two-dimensional speckle tracking echocardiography, and aortic stiffness in middle-aged patients with tile first episode of nonvalvular atrial fibrillation （AF）. Methods： This prospective study included 34 consecutive patients with the first episode of AF, who were admitted to Kartal Kos.;uyolu Research and Training Hospital between May 2013 and October 2015, and 31 age- and gender-matched healthy controls. During the 1^st month （mostly in the first 2 weeks） following their first admission, 34 patients underwent the first pulse wave measurements. Then, 21 patients were recalled for their second pulse wave measurement at 11.8 ± 6.0 months following their initial admission. Echocardiographic and pulse wave findings were compared between these 34 patients and 31 healthy controls. We also compared the pulse wave and echocardiographic findings between the first and second measurements in 21 patients. Results： Pulse wave analysis showed no significant differences between tile AF patients and healthy controls with respect to PWV （ 10.2 ± 2.5 m/s vs. 9.7 ± 2.1 m/s： P = 0.370）, augmentation pressure （9.6 ± 7.4 mmHg vs. 9. 1± 5.7 mmHg; P = 0.740）, and aortic pulse pressure （AoPP; 40.4 ± 14.0 mmHg vs. 42. 1 ±7.6 mmHg, P = 0.550）. The first LA positive peak of strain was inversely related to the augmentation pressure （r 0.30; P = 0.02） and aortic systolic pressure （r - 0.26, P - 0.04）. Comparison between the two consecutive pulse wave measurements in 21 patients showed similar results, except for AoPP. In 21 patients, the AoPP at the second measurement （45.1± 14.1 mmHg） showed a significant increase compared with AoPP at the first measurement （39.0 ±10.6 mmHg, P = 0.028）, which was also higher than that of healthy controls （42.1
